The KNX TP Media Coupler KSC-01L works as a KNX line/area coupler to provide a bi-directional data connection between two KNX TP lines/areas. KNX TP main line and KNX TP subline are coupled having a galvanic isolation in between.
Using the TP Coupler application, KSC-01L can be used as a KNX TP line coupler to connect several KNX TP lines but also as a KNX TP area coupler to connect several TP areas or different KNX TP installation systems via a TP Backbone. Telegram filtering is accomplished according to the installation place in the hierarchy (Physically addressed] Telegrams) and according to the built in filter tables for group communication (Group [oriented] Telegrams). For detailed diagnosis all operational modes/states are shown by a duo-LED display.
Using the TP Repeater application, KSC-01L is able to extend a KNX TP line providing unfiltered data transfer and galvanic isolation between segments. Up to four line segments can form a single KNX TP line by connecting three KSC-01L line repeaters. Each line segment requires its own KNX power supply unit.
To ease commissioning and troubleshooting the Manual Function for short-time telegram filter switch-off and special routing/repetition/confirmation settings are available.
Note: In this document, physically addressed telegrams are named Physical Telegrams.
Note: In this document, group oriented telegrams are named Group Telegrams.

2 1.4 Feature Summary
● KSC-01L supports extended frames and long telegrams up to 239 bytes APDU length. With all Meanwell couplers and UIM interfaces long messages e.g. for energy metering applications and visualization purposes can be processed.
● ACK sending on sent out messages is ETS configurable.
● When there is no IACK response on the subline KSC-01L is able to repeat messages up to three times. Repetitions can be configured for both Physical Telegrams and Group Telegrams via ETS (to ease troubleshooting). After an IACK response no repetition is following and the negative IACK/BUSY failure echanism is maintained.
● Automatic function for switching back to run-time telegram filtering after configurable suspension period (see Manual Mode). This avoids forgetting the reactivation of filtering.
● For an ETS configurable time period, it is possible to switch off telegram filtering by only pressing a button on the device front panel. Without additional ETS download filtering is suspended. This is necessary for running fast diagnostics on site.
● Temporarily suspending telegram filtering eases commissioning and debugging. Without ETS download temporary access to other lines becomes possible.
● In networks with high busload the internal amount of communication buffers are capable of smoothing peeks in the communication load course.
● KSC-01L's ETS database entries are available for ETS4 and later.
2 Operational Description
In network installations KSC-01L can be used as KNX TP area/line coupler or KNX TP line repeater. With its default settings KSC-01L operates as is supposed to.
2.1 TP Coupler Application
When KSC-01L receives telegrams (for example during commissioning) that use Physical Addresses as destination addresses, it compares the Physical Addresses of the receiver with its own physical address and decides on that whether it has to route the telegrams or not.
When KSC-01L receives telegrams that use group addresses as destination addresses, it reacts in accordance with the parameter settings. During normal operation (with default settings), KSC-01L only routes telegrams whose group addresses are entered in the filter table.
3 If KSC-01L routes a telegram and does not receive an acknowledgement, or if a bus device discovers a transmission error, the coupler repeats telegrams up to three times (depending on the corresponding parameter that is set by ETS). With the parameters „Repetitions if errors...“, this function can be configured separately for each line. It is recommended to use the default parameter setting.
If not already configured as “Line Coupler”, the ETS application program “TP Coupler” has to be downloaded to the device. Under the Information tab the configuration setting can be changed by the drop-down menu “Change Application Program”. After changing the configuration setting the filter table entries can be added manually. Updating the application program version can also be done here.
Figure 3: TP Coupler Application Program
2.2 TP Repeater Application
Any received telegram is routed to all lines irrespective of in which line it is processed. Line repeaters make no use of a filter table. It is therefore not important whether the telegram is generated within a line or whether it is sent from an upper line to a lower line via a coupler.
When a transmission error occurs, i.e. due to a wrong receiving Physical Address, the line repeater is able to repeat the telegram up to three times. With the parameter „Physical: Repetition if errors …“ this function can be configured separately for each line.
4 In case of routing a Group Telegram without receiving an acknowledgement, the line repeater repeats telegrams up to three times. With the parameter „Group: Repetitions if errors...“, this function can be configured separately for each line.
If not already configured as Line/Area/BB Repeater, the ETS application program “TP repeater” has to be downloaded to the device. Under the Information tab the configuration setting can be changed by the drop-down menu “Change Application Program”. After changing the configuration setting the filter table entries can be added manually. Updating the application program can also be done here.

2.3.1 Physical Address
For line coupler functionality in a KNX network KSC-01L has to use the correct Physical Address of a line coupler (X.Y.0, 1≤X & Y ≤15). In ETS up to 225 addresses can be defined (from 1.1.0 to 15.15.0).
For area coupler functionality in a KNX network KSC-01L has to use the correct Physical Address of an area coupler (X.0.0, 1≤X≤15). In ETS up to 15 areas can be defined.
If KSC-01L is used in a KNX system for both purposes, it is only necessary to ensure that the KSC-01L used as a line coupler has a line coupler address assigned from a free addressing area. Following figure illustrates the KSC-01L router topology for KNX lines and KNX areas.

Figure 5: KSC-01L Network Example: If an area coupler with address 1.0.0 already exists on the backbone no line coupler with address 1.X.0, 1≤X≤15 can be added here. Even if no line coupler with address 1.1.0 exists on the subline of the 1.0.0 area coupler. Vice versa, if a line coupler with address 1.1.0 already exists in the installation no area coupler with address 1.0.0 can be added.
2.3.2 KNX Topology
Via a line/area coupler up to 15 lines can be connected to a main line called an area. It is possible to have up to 64 bus devices on one line. With use of line repeaters a line can theoretically be extended to 255 bus devices. This means up to four line segments can form a single KNX TP line. But it is common practice on exceeding 64 bus devices to insert a new line instead of extending the originating one.
Note: Each line segment requires its own KNX power supply unit.
Note: Using repeaters on the backbone or on the main line is not allowed.

Figure 6: KSC-01L Network Topology The free tree structure of the KNX topology prevents problems caused by circling telegrams and heavy bus load. So, interconnection between Lines is strictly forbidden.
2.4 Programming
2.4.1 Program Button
To download the desired physical address or an ETS setting the Program Button must be pressed first. Successive pressing the Program Button will turn on and off the Program Mode. LED 7 lighting in red colour indicates Program Mode is active. When Program Mode is active ETS recognizes the device of interest for downloading.
2.4.2 Physical Address Assignment
To commission the device an interface connection (IP, USB) to the KNX bus system is required. The device is supplied with the individual physical address 15.15.0. The KNX product database entry (available for ETS4 and higher) can be downloaded from the Meanwell website and from the KNX Online Catalog.
With the ETS the physical address can be assigned to the device by setting the desired address in the properties window of the ETS. After starting the ETS download and then pressing the Program Button the device restarts itself.
7 Figure 7: ETS Properties Window Note: In this document only the term “physical address” is used. The term “physical address” means the KNX physical address as well as the ETS individual address. Both terms are used by the KNX organization interchangeably.
2.5 Special Functions
The Function Button activates KSC-01L´s special functions. Manual Function and Factory Reset can be activated. It depends on time/number/state the Function Button is being pressed.
2.5.1 Manual Function
During normal operation a rather short press (≈ 3 sec) activates the Manual Function.
When the Manual Function is active, either all Physical Telegrams or all Group Telegrams or both pass the KSC-01L without filtering. After the Switch-off time period has elapsed KSC-01L automatically switches back to normal operation. To configure the Manual Function and set the Switch-off time use the General parameter tab like shown in chapters 3.1 and 4.1. After switching back from Manual Function to normal operation the latest downloaded parameter setting / filter table entries are active again.
2.5.2 Factory Reset
A very long press (≈ 15 sec) of the Function Button soon followed by a second press for some seconds executes the Factory Reset. After the first press the LED display lights different with mixed colour. After the second press all parameters will be set to factory default (incl. physical address). Subsequently, LEDs show the normal display again.
